Dogs are social animals that can spend time with their owners' friends.
Everyone knows about the habit of dogs licking, but usually this "honor" is reserved for family members. However, a dog may also lick strangers who come into your home.
Why does this happen?
In most cases, licking serves as a sign of closeness to a person. In this way, the animal demonstrates that it has a bond with its owner. This behavior is learned from the mother, who licks her puppies.
It is important not to think that the animal has decided to expand its "social circle": the dog licks strangers for a different reason.
Experts claim that dogs' memory works differently. For example, we remember people's appearances, while a dog relies on smell and taste.
If an animal licks a person even once, it will be able to remember them forever.
Thus, the dog uses this simple method to remember that the stranger is not a potential enemy or competitor.
